Sunflower seed oil contains more linoleic acid, and the linoleic acid content and vitamin E are more balanced; rapeseed oil has a high human absorption rate, but the erucic acid in it affects the nutritional value of rapeseed oil . So which one is better, sunflower oil or rapeseed oil?
Which one is better, sunflower oil or rapeseed oil
Introduction to sunflower oil and rapeseed oil
Sunflower Seed oil is made from sunflower seeds pressed from the fruit of sunflower. Sunflower oil is golden in color, clear and transparent, and has a fragrant smell. It is an important edible oil.
Rapeseed oil is what we commonly call rapeseed oil, also called coriander oil. It is a transparent or translucent liquid extracted from the seeds of the cruciferous plant Brassica (rapeseed). Rapeseed oil is golden or brown in color and has a certain pungent smell.
Comparison of the nutritional value of sunflower seed oil and rapeseed oil
The nutritional value of sunflower seed oil
Sunflower seed oil contains sterols, vitamins, linoleic acid, etc. A substance that is beneficial to humans, among which the natural vitamin E content is the highest among all major vegetable oils; while the linoleic acid content can reach about 70%. Sunflower seed oil can reduce serum cholesterol levels, reduce triglyceride levels, and lower blood pressure.
The composition of fatty acids in sunflower seed oil is affected by climate conditions. Sunflower seed oil produced in cold areas contains about 15% oleic acid and about 70% linoleic acid; sunflower seed oil produced in warm areas contains about 65% oleic acid and 70% linoleic acid. Linoleic acid is around 20. The human digestibility of sunflower seed oil is 96.5. It is rich in linoleic acid, which can significantly lower cholesterol, prevent arteriosclerosis and prevent coronary heart disease. In addition, the content of tocopherol a, which has the strongest physiological activity in sunflower oil, is higher than that of ordinary vegetable oils. Moreover, the ratio of linoleic acid content to vitamin E content is relatively balanced, making it easy for the body to absorb and utilize. Therefore, sunflower seed oil is an excellent edible oil with high nutritional value and beneficial to human health.
The nutritional value of rapeseed oil
The oleic acid content of unsaturated fatty acids in high-quality rapeseed oil is second only to olive oil, with an average content of about 61. In addition, rapeseed oil has the highest content of oleic acid and linoleic acid that are beneficial to the human body among all vegetable oils.
Traditional Chinese medicine theory believes that rapeseed oil is sweet, pungent, and warm in nature. It can moisten dryness, kill insects, disperse fire elixirs, and reduce swelling and poison. It is clinically used for roundworm and food-induced intestinal obstruction with good results. .
The human body’s absorption rate of rapeseed oil is very high, up to 99%. Therefore, the unsaturated fatty acids such as linoleic acid and vitamin E and other nutrients it contains can be well absorbed by the body and have certain health benefits. It has the effect of softening blood vessels and delaying aging. Since the raw material for oil extraction is plant seeds, they generally contain a certain amount of seed phospholipids, which are very important for the development of blood vessels, nerves, and brain. Canola oil contains little or no cholesterol, so people who are concerned about cholesterol can safely consume it.
At the same time, rapeseed oil contains a substance harmful to the human body-erucic acid, which may cause fat deposition and damage to the myocardium. Therefore, rapeseed oil should be consumed in moderation.
